A heat generating wall is insulated at the left surface. The right surface is exposed to air having the temperature (T) of 10°C and the heat transfer coefficient (h) of 55 W/m2. C. Twenty-five pin fins with square cross section are attached to the right surface of the wall. The thickness of the wall (Lw) is 24 cm. The height and the width of the wall are both 50 cm. Each fin has the thickness (t) of 5 cm and the length (Lt) of 12 cm. Thermal conductivities of the wall and the fins are kw = 60 W/m.°C and kr= 150 W/m.°C. What is the volumetric rate of heat generation (egen) if the maximum temperature of the wall is 200°C?

Question
Transcribed Image Text:3. A heat generating wall is insulated at the left surface. The right surface is
exposed to air having the temperature (T) of 10°C and the heat transfer
coefficient (h) of 55 W/m2.°C. Twenty-five pin fins with square cross section
are attached to the right surface of the wall. The thickness of the wall (Lw) is
24 cm. The height and the width of the wall are both 50 cm. Each fin has the
thickness (t) of 5 cm and the length (Lt) of 12 cm. Thermal conductivities of
the wall and the fins are kw = 60 W/m.°C and kr= 150 W/m.°C. What is the
volumetric rate of heat generation (egen) if the maximum temperature of the
wall is 200°C?
